This book contains the extended abstracts of 90 papers and posters presented at the 2nd Biannual meeting of the International Research Society of Spinal Deformities, which was concerned with fundamental issues relating to the detection, diagnosis, prevention and treatment of spinal deformities, especially in children. It provides readers with the latest information and scientific ideas with an emphasis on three-dimensional and morphological aspects of spine and trunk asymmetry, improved understanding of mechanisms underlying the etiology, pathomechanism, and treatment of spinal deformity. The International Research Society of Spinal Deformities (IRSSD) was established in 1994 to advance the study and research into Spinal Deformities by providing a forum for the presentation and encouragement of research relating to spinal deformity and to disseminate the results of such research.
